2007 Mercedes-Benz CLS 3.0L Diesel · AF07 YYC

The vehicle most recently passed its MOT on 9 September 2025, though this followed a failure involving a dangerous brake pipe leak. The overall maintenance trend is concerning, as the vehicle has failed its initial MOT inspection every year since 2022. This pattern of reactive repairs suggests that the previous owner has waited for components to reach a state of failure or danger before addressing them, rather than following a preventative maintenance schedule. With 165,329 miles recorded over 19 years, the vehicle has averaged approximately 8,702 miles per year. This is considered typical usage for its age, implying the car has been used regularly rather than sitting idle. However, this level of mileage on a luxury chassis means that high wear consumables and complex drivetrain components are likely nearing the end of their natural service life, necessitating a rigorous check of the vehicle's mechanical health. Prospective buyers should pay close attention to the braking system and chassis. The recent dangerous failure regarding a leaking nearside rear brake pipe suggests potential corrosion within the hydraulic lines. You should inspect the underbody for signs of rust and check the brake fluid reservoir level. During a test drive, feel for any sponginess in the brake pedal or shuddering under deceleration. Furthermore, the history of fractured coil springs and worn ball joints indicates a general degradation of the suspension system. Listen for metallic clunks or knocks when traversing uneven surfaces and inspect the tyres for uneven wear, which often points to failing suspension bushes or incorrect wheel alignment. Beyond the recorded failures, the deteriorated headlamp lenses noted in the latest advisory should be inspected for heavy oxidation, as this significantly impairs nighttime visibility. Given the age and mileage, it is imperative to verify the service history for evidence of regular engine oil changes and automatic transmission fluid replacements. You should also examine the condition of the rubber seals and window trims for perishing, and check the 12V battery health, as these luxury models are highly sensitive to voltage drops which can trigger spurious electronic faults across the dashboard.
